That's just 10% what the plant emits, but Jones argues Skyonic should get credit for avoiding 220, 000 tons of carbon dioxide because it is creating products, like hydrogen, that would otherwise come from natural gas and release lots of carbon dioxide.

Starting with two silicon wafers, Soitec machines coat the surface of one with silicon dioxide insulator and embed inside it a thin fault line of hydrogen atoms anywhere from 100 to 20, 000 nanometers below the surface, depending on customers' desired wafer thickness.
